I was able to transfer a folder of MP3’s totaling 1.56GB to the drive via Firewire from my iMac G5 in a staggering one minute and 27 seconds. This is an incredibly fast speed. I believe that a folder of files is a much better representation of transfer speed then a single file, because most users will be backing up multiple small files not big files. However, in case you were curious, I did transfer a single 4GB file to the drive, and it took a meager two minutes and 59 seconds, which really is incredibly fast. USB 2.0 transfers for the same files took one minute and 49 seconds, and three minutes 24 seconds, respectively.

These tests clearly show that this drive is capable of some of the best speeds external hard drives have seen, without a doubt due to its large cache buffer, and fast RPM speeds. If you are looking for a drive that is speedy, this is by far one of the best offerings out there.
